1/4 mile times

[jonota]

Took the LS and the T/A to the track today. I wasn't impressed w/ the LS's times. Last time my best was a 1.285 RT, 2.433 60 ft, and a 15.889@88.71. This time, w/ the new plugs best was a .834 RT, a 2.543 60 ft, and a 15.927@89.44. The car is stock except for a K&N filter and the Bosch plugs. Going to run some fuel system cleaner through it this weekend and maybe take it back out at the end of september. Anyone else have some time so I can compare? I feel like this car should be running a little faster....

Jonota,

A lot of factors play into time differences such as temperature, humidity and gas. I know the first time I dynoed my car I was less than thrilled but the second time was better. I'd say cooler weather helps tremendously. What time of day did you run each time?

[bill5]

Ken,
You and I should be pretty close, performance-wise. Does the Dyno evaluate HP? Just curious what you got on your best run.

Tooled around last night with some buddies... Audi A6 4.2, Honda S2000 and a 911. To be frank, I felt a little sluggish... maintained that "LS Smile", however!

Bill,

You'll feel real sluggish with the S2000 and 911. Those are street performance machines. If you gave them a run for their money then that's what counts. Also, the LS will be more capable in the twisties and would compete much better there. The LS was not designed as a drag car but rather an all around luxury sedan vehicle.

I posted my dyno sheet in another thread here. Check it out.

[Quik LS]

my best time is 13.9350 @ 109.04

had alot of trouble putting the power down in the first 80'.

yes - is was with spray

It was a nighttime run, but here in Hawaii that doesn't mean it's cool... temps never get below the mid to upper 70's really.

Quik LS- what all do you have done? A 110mph trap speed should be quite a bit faster than a 13.9.... get some slicks!

[Quik LS]

I spun for a looooong time off the line...

100 shot of nawz. That was back in Jan. Since then I have removed the NOS in favor of auto-crossing 2x monthly. so I'm focusing now more on stopping and handling. The LS can't do much better then that in a 1/4 mile - but auto-crossing really brings out the handling of the car - were it shines.

I have about $9k in tweaks to my LS

I read an interesting article on dyno's a month or 2 ago in c&d. It was talking about newer cars that lose alot of power on a dyno if they are looking at air temp&flow liek the bmw they had. But said even on a normal car the lack adequate air flow which is tremendously expensive to properly apply power can be lost due the radiator not ebing able to dissipate the heat very well. They said conditions have alot more than most people would think to do with dyno's and power in general on cars. Also you may want to try a good dual stage foam filter as opposed to the k&n as from what i have found the k&n's don't do a very good job of filtering. I just picked up a true-flow cone filter for my 98 tc to replace the k&n cone.

[Desert Stallion]

Yep, K&N's suck rocks.

Anyway, the car with good tires should be low 15's stock. The problem is they don't have the right tires or suspension to do well in the 1/4.

Now, slap on some 15-16" rims with BFG drag radials, get 'em hot, stall the convertor before leaving the line, and get your R/T's down. There's about a full second to be had in your ET's by just cutting half a second off your 60' times, and that's where the sticky tires come in.

Good luck.

(Hey, this may be my first venturing into the LS realm. :D )

[pro-five-oh]

Didn't the 2002-05 LS have a much freer flowing airbox? That would be a worthwhile mod for an older model.

What rpm were you launching at, jonota?

[Quik LS]

in '03 the engine changed - so none of the intake will fit a 00-01.

The best I could do on the intake side was to go with a CIA, big cone filter, seal it off from the engine heat and then add a hood scoop.

[pro-five-oh]

Ok, I am getting some conflicting information here. I found what 351CJ previously posted, take a look at it. Thanks! smile.gif

quote:The air box for the air cleaner was actually changed at the start of the 2002 model year. You can buy a 2002 air box and put it on your 2001 LS. Howver it will be somewhat expensive as the only way you can buy the airbox is a complete assembly with the top cover including the mass airflow sensor. Lowest price I've heard is about $150 from internet places such as fordpartsnetwork.com

The new airbox and a new exhaust system is why the 2002 V6 has more HP than the 2000 & 2001. Rumors are that the airbox adds another 5 HP to the 2002 V8, but Lincoln choose not to change the V8 HP rating so the advertised increase for 2003 would be more dramatic.

[Desert Stallion]

I think the LS would be a cool platform to modify into a nice performance street car. Unforunately it'll be another few years before their prices come down into the realm of feasable mod-intended cars.

Oh well, lots of cheap VII' and VIII's out there. :D

not conflicting - the 02 had a more 'open' airbox, starting in 03 the new engines came out and none of the intakes are the same.

you could put an 02 airbox in - but why, it is only slighty better? Replace it with a CIA.

[Desert Stallion]

Because most CIA's use K&N type air filters which will effectively trash the motor or the MAF over a short period of time, whereas the OEM type filters are pretty damn good at filtering the incoming air.

Where did that come from???? I've been running HARD on those setups for years, can't say I've had a motor or MAF trashed yet, and my LT1's MAF is NOTORIOUS for being fickle. CAI's might allow a SMALL amount more in, but in most cases that I've personally seen, they make very little difference. If the CAI is INSTALLED incorrectly, it can trash everything, but that is the case with any intake part.

I was launching at idle or 1300 w/ braking. Neither provided much traction.... and launching with the traction control... well that was just funny.

Jonota,

Are you stating that the CAI only makes a difference in performance or just air flow? I have proven that the CAI contributes to about 15 additional HP and about the same in torque. Until someone comes out with a supercharger for the LS, the CAI is the best bang for your dollar. Of course adding a cat-back exhaust will give you about the same increase in HP and torque that the CAI gives.

I posted my dyno compared to a bone-stock 2003 LS in another thread here. I'm sure Lou (QuikLS) will agree.

[Desert Stallion]

It may be a bit different living in Hawaii than here in Hell's kitchen where dust and dirt is a fact of life, but a couple people in the local Mustang club did a test comparing how much dirt a 'properly serviced' cotton filter let in vs about a half dozen other filters, including OEM, as well as a dyno series. The cotton filter allowed approx. 5HP at the top end, compared to OEM paper filter, but let in an absolutely amazing amount of dirt.

Now, I don't know about you, but even my sensative butt would never feel 5 top-end horsies while driving my car daily, especially since it never gets near the top-end.

There's a reason the handful of heavy equipment and track companies that switched to cotton filters switched back shortly after. The filters just don't filter well, and were causing more frequent need for oil changes as well as some added wear, and when serviced improperly it's real easy to muck up a MAF meter. Had to deal with that a couple times while working for a local speed shop last year. :rolleyes:

[jonota]

kgie: I meant in cleanliness. I know that on some applications a CAI can provide quite a bit of improvement, as it appears to on the LS. There are some applications where it does VERY little or no improvement.

Desert Stallion: I've been in Texas, South Carolina, and Hawaii, and Hawaii is VERY dirty/dusty. I have to wash the LS daily almost to keep it looking halfway decent. My wife works with horses and drives it up a dirt road every day. My Trans Am has had a junk yard K&N off of a 129k mile Camaro for 2 years now, and I haven't serviced it yet. I've attempted to clean the MAF as troubleshooting a problem before, and a cotton swab with alcohol on it came back perfectly white. There are many different applications for filters, and a test of just one is not conclusive of all...

Understand completely!

[Desert Stallion]

It's not just one, I've seen it on at least a dozen different applications with dozens of cars within those applications, not to mention the fact that ALL heavy equipment companies that were using them have discontinued their use to return to an OEM style filter.

[Lamar]

Has anyone heard or read how well the UPR Big Mouth Stainless Steel Mesh filters filter the air? Do they filter as well as OEM?

[sqfanatic]

would properly (or more often) cleaning and oiling the K&N or other CAI cone filters help?

I see the High end filters $300 come with a splash shield usually to prevent water or other thigns from getting on the cotton. I believe it is only this type of splash that is what starts letting in the dirt.

Properly oiled K&N should be great, but I'm going to use the one that fits in my OEM box so I'm sure there's no splash risk. :)
